This discovery is not only remarkable in its novelty, but this also demonstrates that eye cells could have existed for at least the last 300 million years. Furthermore this study also suggests that ancient fish species actually saw in color as well, as described by the study’s scientists.

What we know about human vision is that our eyes rely on pigments that absorb light. Each of these pigments rest within the cells known as rods and cones.
